You can try to use an animation library like GSAP to translate the camera towards the selected 3D object. The code for this looks like so:

gsap.to( camera.position, {
    duration: 1, // seconds
    x: target.x,
    y: target.y,
    z: target.z,
    onUpdate: function() {
        camera.lookAt( center );
    }
} );

The target vector is the destination that you have to define in the first place. After that you can put the above code at the place where console.log( 'Intersection:', intersects[ 0 ] ); is now executed.
